分析問題

音頻url

點入某個音樂的播放界面，通過F12-Network，分析數(shù)據(jù)，可以看到有一個index.php?..返回數(shù)據(jù)中有一個play_url，打開后正是我們需要的音頻。

查看該url的headers，其params參數(shù)如下，通過反復(fù)不同的幾次嘗試，得知r、callback、dfid、mid、platid這幾項不變，而通過初步的requests嘗試，發(fā)現(xiàn)最后一項'_'可有可無，改變的只有hash和album_id兩項。

r: play/getdata
callback: jQuery1910861615852090795_1612578519454
hash: EF0DA656831F08B1FD2CB855BC38ED2C
dfid: 0Q0Clh1IcZaG3ey1J70RaTiL
mid: b6cf66837b18642cc269390b066649dc
platid: 4
album_id: 41669581
_: 1612578519455

搜索url

得知改變的只有兩項后，那就容易多了，在搜索歌曲界面Network，發(fā)現(xiàn)song?...該url返回值中有hash和album_id存在，我們之后只用搜索結(jié)果第一項（一般要搜的歌曲排名第一）。

同樣分析其params參數(shù)，改變的只有keyword、signature、clienttime、mid、uuid。后三者可以比較容易看出其為毫秒級時間戳（13位），keyword也挺容易明白，signature哪里找呢？通過全局搜索signature，發(fā)現(xiàn)有一個js文件中含有該關(guān)鍵詞。

在274行發(fā)現(xiàn)h.signature = faultylabs.MD5(o.join("")),初步理解為signature是o內(nèi)部元素拼接成字符串，對其加上斷點并將o加入watch。

在watch里不難發(fā)現(xiàn)o為一個長度為20的數(shù)組，之后我們按之前理解將字符串拼接。

之后要js解密，這誰會？反正我不會 0.0，那也有辦法，用python調(diào)用js文件。在274行分析為md5加密，往前找看看有沒有相關(guān)函數(shù)，果真有一個，將其保存為kugou.js
